Interview Prompt
The performance team is hunting the latency tail on the API gateway, where the request logs record the HTTP `method` inconsistently, sometimes in lowercase. For each method, average the `latency` of its five slowest calls, and list the methods from the highest average down.
Summary
Averages hide the pain. The tail is where SLOs live.
